The machine has been running decent for about a month now... since we last had it worked on. Suddenly, it is giving three different errors. The first to pop up is a "coolant motor overload", followed closely by a "Emergency Stop Activated" message. Two things... the coolant motor is not in use and no one has hit the emergency stop button. A third error did come up but only once so I am not sure it is significant or related in any way to the other two errors which come up each time the machine is turned on. I am new to this machine so am not at all familiar with it. If anyone has suggestions on what the issue could be... or issues. Please let me know. Thanks!!
